2 claims. (ci. 229-34) l This invention relates to folded-blank boxtrays of the kind in which two of the sides have corner flaps foldedinward and secured by folding over upper marginal flaps of the'other twosides.

The invention has for its principal object to provide a box tray of theabove type having corner constructions which are strong and durable andof neat and attractive appearance, which will dispense with the need forseparate fasteners vand which will permit the box tray to be quickly andeasily set up and knocked down.

The invention consists in providingtwo of the sides of a box tray of theabove type with end naps that are folded around the corners of said trayagainst the outer faces of the other two sides thereof and are thencefolded downwardly over the upper' edges of said other two sides andagainst the inner faces thereof in inside corner forming relationto thedownturned upper marginal naps of said two first mentioned sides; italso consists in shaping the adjacent inside corner forming edges ofsaid downturned end and upper marginal flaps so that each locks theother in place; and it also consists in the' folded-blank box tray andin the parts and combinations and arrangements of parts hereinafterdescribed and claimed.

In the accompanying drawing. which forms part of this specification andwherein like symbols refer to like parts wherever they occur,

Fig. 1 is a perspective view of a folded-blank box tray embodying myinvention,

Fig. 2 is a plan view of the blank from which the box tray is formed, K'

Fig. 3 is an enlarged fragmentary vertical crosssection view on the line3-3 in Fig. 1,

Figs. 4 and 5 are enlarged fragmentary horizontal sectional views on thelines I-I and 5 5, respectively, in Fig. 1; and

Fig. 6 is an enlarged fragmentary vertical sectional view on the line6-8 in Fig. 1. In the accompanying drawing, my invention is shown'embodied in a folded-blank box tray which is adapted to form one of thetwo collapsible sections of a telescopic box. The box tray is made froma rectangular blank A of corrugated board, fiberboard or other bendablematerial which is divided by a longitudinal score vline I along eachside margin and b y transverse score lines Zand 3 adjacent to each endmargin into a bottompanel 4, side wall panels 5 and end wall panels 6with marginal flaps 1. The blank is slit or notched, as at 8, along thelongitudinal score lines I from the ends of said blank to the outermosttransverse score lines 3. The blank is also slit or notched diagonally,as at 9, along its sides from the ends of the outermost transverse scorelines 3 to the points where the longitudinal score lines I intersect theinnermost transverse score lines 2. 'I'he diagonal slits 9 formtriangular flaps IU at the ends of the side wall panels 5; and saiddiagonal slits, together with the longitudinal slits form locking flapsII having triangular portions I'2 connected to the ends of the end wallpanels B and rectangular free end portions I3 connected to saidtriangular portions along the'outermost transverse score lines 3. Asshown in the drawing, the longitudinal slits 8 are offset, as at I4,midway of their length to provide notches I5 andtongues I6 along theends of the `flaps I and a reverse arrangement of notches I5 and tonguesI6al along the inner edges of the rectangular free end portions I3 ofthe' flaps II.

The above box tray is set up or erected by first folding the` side wallpanels 5 upwardly, then folding the triangular end flaps I0 of said sidewall panels inwardly at right angles thereto, and then' folding the endwall panels 6 upwardly against the inturned end naps. The uppermarginal' flaps 'l of the end wall panels 6 -are then folded downwardlyon the inner side thereof in overlapping relation to the inturnedtriangular end flaps vIll of the side wall panels 5, with the loweredges of said upper marginal flaps seating against the bottom panel 4and with their tongue portions I6 in frictional engagement with theinner side faces of said side wall panels. The triangular portions I2 of the end flaps II ofthe end wall panels 6 are then folded around thecorners of the tray against the outer side faces of the side wall panels5, after which the rectangular free end portions 'I3 of said end flapsare bent downwardly over the upper edges of said side wall panels andagainst the inner side faces thereof with the lower edges of saiddownwardly folded portions seating on the bottom panel. In this foldedposition of the portions I3 of the aps II', the tongues ISB thereof seatin the notches I5 in the naps 1. and the tongues I6 seat in therilotches I5 of the folded portions I3 of the flaps The hereinbeforedescribed folded-blank box tray construction has several importantadvantages. The blank may be shipped in the flat and quickly and easilyset up without the use of separate fastening members. The folded cornerflap arrangement greatly increases the strength and rigidity of the boxat the corners thereof and thus enables the boxes to be stacked and towithstand rough handling. The exposed corner 3 portions of the lockingilaps improve the appearance ot the tray; and the interlocked tonguesand recesses along the adjacent ends of the downturned upper marginalflaps and end aps of the end wall panels serve to rmly hold said flapsin locking position.

Obviously, the hereinbefore described foldedblank box tray constructionadmits of considerable modication without departing from the invention.Therefore, I do not wish to be limited to the precise construction shownand described.

What I claim is:

l. A rectangular folded-blank box tray comprising a bottom panel, twoside wall panels having inturned end flaps, and two end wall panelsdisposed alongside of said inturned end ilaps against the outer facesthereof and having upper marginal aps folded downwardly over said 4fined at each corner of said blank by a single slit which is oisetlaterally intermediate between its ends to provide said interilttlnsnotches and tongues at the corresponding corner of said folded-blank boxtray.

2. A rectangular box tray blank which is divided by a longitudinal scoreline along each side margin and two transverse score lines adjacent toeach end margin into a bottom panel, side wall panels and end wallpanels with marginal flaps, slits extending along said longitudinalscore lines from the ends oi' said blank to the outermost transversescorelines, and slits extending diagonally from the ends of theoutermost score lines to points of intersection ot said longitudi- V nalscore lines and said innermost transverse inturned end flaps against'theinner sides thereoi', said end wall panels having corner locking endiiaps with inner portions that are folded around said side wall panelsagainst the outer sides thereof and outer portions that are foldeddownwardly over the upper edges ol' said side wall panels and againstthe inner faces' thereof. the adjacent ends of said downwardly foldedupper marginal flaps of said end wall panels and said downwardly foldedouter portions of said corner locking end aps of said side wall panelsbeing each formed with a notch and a tongue, the tongue of each of saidadjacent ends tting within the notch in the other of said adjacent ends,said folded-blank box tray being made from a one-piece rectangular blankwhich is divided by slits and score lines into said bottom panel, saidside wall panels and their end flaps and said end wall panels and theirupper marginal flaps and corner locking end flaps, said adjacent ends ofsaid upper marginal flaps and said outer portions of said corner lockingend aps being descore lines, said slits forming triangular end flaps atthe ends of said side wall panels and flaps at the ends oi' said endwall panels having triangular inner portions and rectangular outerportions, said longitudinal slits deilning the adjacent edges of themarginal flaps oi said end wall panels and said rectangular outerportion of said triangular end flaps-,said longitudinal slits beingoffset laterally intermediate between their ends to provide along eachof said adjacent edges a notch and a tongue, the tongue on each of saidadjacent edges being disposed opposite the notch in the other of saidadjacent edges.
